将数据文本文件加载到多维数组中，然后将内容复制到文本框中 [英] Load a data text file into a multidimentional array then copie the content into textboxes

问题描述

亲爱的代码项目成员，
我是Visual C#的初学者，我希望您能解决这个问题，这对于像您这样的高级社区来说太简单了，但对我来说却很困难.

问题:
我有一个文本文件，其中包含14列和3500多行整数.我需要通过单击按钮来读取该文件，然后将全部内容加载到多维数组中.从该数组中将加载14个文本框.然后，我需要该内容每50毫秒更改一次.我将使用此应用程序创建一个套接字，通过该套接字将数据发送到控制其轨迹的机器人.

最好的问候

Dear code project members,
I''m a very beginer in Visual C# and I would like you to help me with this problem, which is too simple for a high level community like you but very difficult for me.

The problem:
I have a text file which contains 14 columns and more than 3500 rows of integers. I need to read that file by the click of a button and then load the whole contents into a multi dimensional array. From this array 14 textboxes will be loaded. Then I need that content to change every 50ms. I''ll use this application to create a socket over which I''ll send the data to a robot controlling a its trajectory.

Best regards

推荐答案

如果您需要有关创建，处理数组的信息: System.IO.File [^ ]
如果您不满意文件类: System.IO.TextReader [ ^ ]
如果需要通用计时器: System.Timers.Timer [ ^ ]
计时器类的替代方法有使用线程和使用thread.sleep来管理计时检出系统. Threading.Thread [^ ]在CodeProject中也有很多文章和问答.例如如何将ref参数传递给线程 [ ^ ].
祝你好运.

If you need info about creating, handling arrays: Array tutorial[^]
If you need info about general file reading stuff like ReadAllText ReadAllLines etc:System.IO.File[^]
If you arent happy with just File class: System.IO.TextReader[^]
If you want a general purpose timer:System.Timers.Timer[^]
There are alternatives to timer class like using threads and use thread.sleep to manage timing checkout System.Threading.Thread[^] also there are many articles and Q&A in CodeProject as well. For instance How to pass ref parameter to the thread[^].
Good luck.
